AUTOMATED DEVICE FOR ELECTROCHEMICAL MEASUREMENTS AND APPLICATION TO THE SYSTEM PT SOLID ELECTROLYTE/

An automated device for voltammetric measurements at a prescribed set of constant temperatures was put together in our institute. It allows one to take steady-state current-potential curves in the potentiostati c or galvanostatic mode, to do cyclic voltammetry or coulometry at con stant potential or to measure the potential-time dependence at a const ant current. A special holder for the solid electrolyte was constructe d. Voltammetric measurements on yttrium stabilized zirconia and of the new oxygen ion conductor BICUVOX.10 are presented as examples.
